Abstract

The invention discloses a high-toughness, durable and antiskid steel bridge deck pavement structure and a construction method thereof. The steel bridge deck pavement structure comprises a steel bridgedeck steel plate; a bonding bottom layer, a buffer layer, an adhesion layer and a wearing layer are sequentially laid on the surface of the steel bridge deck steel plate from bottom to top; the buffer layer and the wearing layer are both made of high-toughness modified asphalt concrete composed of aggregate, filler and asphalt cement, the thickness of the buffer layer is 1-3 cm, and the thicknessof the wearing layer is 2-3 cm. The bridge deck pavement structure has good high-temperature rut resistance, fatigue durability, skid resistance, bonding strength and deformation compliance, comparedwith epoxy asphalt concrete, the engineering cost is greatly reduced, the construction process is simple, and later maintenance is convenient.

Description

technical field

[0001] The invention relates to the technical fields of road construction materials and engineering, in particular to a high-toughness, durability and anti-skid steel bridge deck pavement structure and a construction method thereof. Background technique

[0002] Steel box girder has significant advantages such as light weight and convenient erection, and is widely used in the construction of bridges and municipal projects at home and abroad. Steel box girder bridge deck pavement is the protective layer of the bridge deck and the structural layer that provides road service functions, and plays an important role in the durability of the bridge, ensuring the safety and comfort of driving, and economic and social benefits. Combined with my country's climate environment, the external environment with serious overload problems and the complex stress system of orthotropic steel bridge decks, the following requirements are put forward for the pavement layer: 1) Good ...
